New hope for Hard-to-Treat myeloma: experimental drug surzetoclax enters human trials

NCT ID NCT06953960

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is testing an experimental drug called surzetoclax, alone or combined with other cancer drugs, in about 130 adults with multiple myeloma that has returned or stopped responding to prior treatments. The goal is to find the safest dose and see if it can shrink or control the cancer. Participants will receive the drug as pills or injections and be closely monitored for side effects and disease changes over about 4.5 years.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

surzetoclax (ABBV-453)

What this could lead to

If successful, this could lead to a new treatment option for people with multiple myeloma that has stopped responding to other therapies.

What could go wrong

This is an early-phase trial (Phase 1/2) with a small number of participants, so the drug may not prove effective or may have unexpected side effects. The study also involves multiple drug combinations, making it harder to isolate the benefit of surzetoclax alone.
